The rectangle is 16 inches by 25 inches. If the scale is 4 in :5 ft what is the length and width of the rectangle in feet.
Alenkasestr [34]

Answer:

The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

Step-by-step explanation:

Let the scale be 4\,in\,:\,5\,ft and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale (r), measured in inches per feet, is equivalent to the following rational number:

r = \frac{4\,in}{5\,ft}

We can convert each length by dividing it by scale factor. That is:

Length

l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }

l' = 20\,ft

Width

w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }

w' = 31.25\,ft

The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

The cost to visit a famous tourist attraction in Russia is 442.25 Rubles. What is the cost in USD if the exchange rate is 3 USD
Lubov Fominskaja [6]

Answer:

$14.5

Step-by-step explanation:

Given data

Cost for the visit=442.25 Rubles

exchange rate

3 USD= 91.5 Rubles

but 1 USD= 91.5/3

=  30.5

Therefore if 1 USD is 30.5 Rubles

         Then   xUSD is  442.25 Rubles

cross multiply

30.5x= 442.25

divide both sides by 30.5

x= 442.25/30.5

x=14.5USD

The cost of the attraction is $14.5
